The invention relates to sterilizers and has for an object the provision of a simple and inexpensive flame-heated dry-heat sterilizer which is particularly adapted for the sterilization of brushes, such as tooth-brushes.

The invention further consists in the several features hereinafter set forth and more particularly defined by the annexed claims.

In the accompanying drawing Fig. 1 is a perspective view of a brush sterilizer embodying the invention;

Fig. 2 is a side view of the sterilizer with a tooth-brush mounted therein, parts of the sterilizer .being broken away and parts being shown in section;

Fig. 8 is a top plan view of the sterilizer, and V Fig. 4 is a transverse sectional viewof a modified form of sterilizer.

In the drawing, the numeral 10 designates a flat handle-forming frame, which may be constructed of sheet metal. At one end of the frame is secured a heat-conducting sheath 11 of U-shaped cross-section forming therein a sterilizing chamber receiving the bristle portion of a brush 12, in the present instance indicated to be a tooth-brush. The outer end of the sheath 11 ispreferably, though not necessarily, closed, as seen in Fig. 2. The edge portions of the sheath are provided .with lips 13 which pass through slots 14:

formed in the frame 10 and are bent inwardly on the outer face of the frame, as seen in Fig. 3, to anchor the sheath in place.

In the modified form OfStEI'lllZGl shown in Fig. 4, the sheath 11 is provided at its flame about the bristles without danger of scorching the bristlesor other parts of the brush, since the flame does not pass through the screen. The flame may be produced in any one of various ways convenient to the user and need be applied for only a few sec impinging thereon and adapted to receive therein an article-to be sterilized, said screen casing permitting the flow therethrough of hot sterilizing gases but preventing the direct access of the flame to the article.

3. A dry heat sterilizer comprising a sheet F metal supporting member forming a handle at one end, a metal screen sheath adaptedto be heated by a flame impinging thereon and having edge portions secured to the other end of said supporting member to form therewith a compartment adapted to receive an article to be sterilized, said sheath permitting the flow therethrough of hot sterilizing gases but preventing the direct access of the flame to the article. 1

4. A dry heat sterilizer comprising an airpervious metal screencasing adapted to receive therein an. article to be sterilized and adapted to be exteriorly heated by an adjacent incandescent heat source to a nonscorching sterilizing temperature.

In testimony whereof I affix my signature. 1
